I am trying to learn 3D Analyst and am using the tutorial data to work through the exercises in the tutorial. In exercises 2 and 3, I am instructed to extrude the well points into vertical lines, facility polygons, and extrude polygons from the "Thyroid cancer rates." I complete each step exactly as explained in the tutorial, but it doesn't do what the text says it should do. Anybody else have this problem and what do I do to make it work correctly?
